The object of the present invention is't-o provide askate of thisgeneral type having relatively large wheels yet withja lowfcentre I '7of'support, which is economical in manufac- 9 ture, and which isoflight, rigid and durable construction. Y

With these objects in view, the present invention consists in the skatehereinafter [de-c scribed and particularly defined in the claims. r

. Having ,thus describedjthe invention", what I isclaimedis: 1

l. A skate comprising an integral frame having a horizontal sole plate,a vertical; red inforcing rib for the sole plate and integral therewiththroughout the length of the plate,

skate as applied to a shoe; Fig. '2 is a bottom plan view of the skate;and Fig. 3 is a section on line 3-3 of Fig. 2. I I The illustratedembodiment of the inven- 7 tion comprises a skate having a frame orfoot-supporting portion indicated generally at 4, on which are mountedwheels 6 at opposite ends thereof and in the longitudinal median planeof the foot. The frame is adapted for attachment toa shoe 8'of anydesired a form, by means of rivets. I

The frame comprises an integral casting, preferably a die casting, Itconsists of'a sole plate 10 for engagement with the sole of the shoe,andthis plate is'considerably narrower than the shoe to which it is tobe attached in order that it will not strike upon thesura face of theground when theskate is inclined] V to one side or the other,-either. instraight "away speed skating or in making abrupt changes of direction. Alongitudinal medial, vertical reinforcing rib 12 is formed on the tframe for the purpose of lending strength to the entire structure,while'permitting manufacture of the skate from material of light weight,such as is usually employed in the die casting art. At each end of theskate is a yokeil lwhich extends upwardly and longitudinally from theframe, being formed as a continuation of the reinforcing rib 12. Thewheels arejournaled in the ends of the yokes and by the upward curvatureof the yokes as w illustrated in Fig. 1, the center of gravity both endsof the ing integral frame having a sole plate adapt andyokes extendingupwardly and longitudinallyfrom the sole plate and rib 011 frame andlying wholly above the lowermostpoint of the rib, and

wheels jounaled in the yokes.

2. A skate comprising a rigid and unyield,

ed for attachment to a shoe and of, less width than thatof the shoe towhich it isto be attached, and yokes formed integrally with the soleplate and extending upwardly and outwardly from opposite ends of thesoleplate, 59

.the plate at each end overlying and merging into the yokes. v

3; A skate comprising an integral casting having a sole plate and amedial, vertical,

yokes and wheels journaled in the I reinforcingrib,'the rib beingextended longitudinally at opposite ends of the soleplate it i toformyokes, the yokes extending upwardly with their, free endslocated asubstantial dis- A tance above the sole plate, and wheels journaled inthe yokes.

4. A skate. comprising a rigid integral casting having a sole plate, avertical reinforcing rib below the sole plate, yokes formed integrallywith the sole plate and the rib 9 A and extending outwardly and upwardlyfrom opposite ends thereof, the sole plate at each end merging into theyokes adjacent the rib with the top surface of the plate coincident withthe top surface of the yokes at the point 1 of merger, the yokes beingof a width at least as great as that of the rib, and wheels journaled inthe yokes, the center of gravity of the skate being below the axis ofrotation of 5 the wheels.

5. A roller skatehaving but two wheels arranged one in front of theother, a rigid foot-support located between said wheels and located in aplane below a plane assing through the centers of the said whee s, saidfoot su'pport being-formed lon tudinally to resent an up er surface whicis lower adacent to the ront Wheel than it is adjacent to the rear wheelthereb to conform substantially with a foot of t e wearer and yokesextending from the foot-support and attached to the wheels to supportsaid footsupport between them.

6. A roller skate having afoot-su porting 29 plate, a reinforcini ribbelow said oot-suporting plate, yo es extending upwardly rom beneath theends of the foot-supporting gate and having wheelsqournaled n their eeends, the centers ot saidwheels being 533 located substantial distancesabove the plane of saidffoot-supporting plate.
